Membership cancellation

I requested for my Virgin Active gym membership to be cancelled on 29 June 2021. The only email response I received was an acknowledgement of receipt email. I did a follow-up on my request and there was still no response. My emails for membership cancellation were send to *** mailbox.

I have not been to gym since December 2019 and unfortunately had a leg accident in March 2021. I am still in my recovery process and will not be attending gym anytime soon. The lack of response from virgin active shows no regard for customers. I want my membership cancelled and backdated to the day I sent my cancellation email to them. please assist me.
